SOGKET.-

T all whom it may concern:

Be it known that 1, WILLIAM S. HADAW'AY, J r., a citizen of'the United States of America, and a resident of New Rochelle, Westchester county, and State of New York, United States of America, have invented certain new and useful Improvements in Sockets, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to electrical contacts and particularly to fixtures or sockets for supporting removable heating or lighting units. 1

One object of my invention is to provide a socket of the aforesaid character that shall M be simple and-inexpensive to construct and adapted to be secured to a sheet metal plate or base in close proximity to other similar fixtures.

Other objects and advantages of my-in- Vention will be set forth hereinafter, and in order that my invention may be thoroughly understood, I will now proceed to describe the same in the following specification, and

thenpoint out the novel features in appended claimsi Referring to the drawings: Figure 1 is a partially sectional elevation of a socket constructed inaccordance with my invention and secured to a perforated supporting .plate, arranged to receive additional sockets of the same character. A sectional elevation of the same parts is shown on a larger scale in Fig. 2. Fig. 3 is atop plan view and Fig. 4 a bottom plan view of the same socket. [The socket illustrated comprises a cup- ,fshaped body 10 of sheet metal adapted to be to secured, to and supported by a base plate 15, a socket contact 20 and terminal members t 25 and, 30. The cup-shaped body 10 is provided my ith a central opening 11 in its base ,and air, en-largementl2 near its open end having an extruded annular flange 13. The ilangeixonstitutes a bead flattened into an outwardly extending rib and the size of the enlargement beyond the rib is such that it extends freely through the hole 1% in the b0 base plate 15.

The socket contact 20 is provided with Specification of Letters Eatent.

at its inner end which is reinforced by a metal ring 23.

The terminal member 25 comprises a perforated arm 26 which is separated from the base of the body member by an insulating disk 28 and is secured in position adjacent to the base by means of rivets 27 which extend through suitable holes in the flange 22 and the ring 23 and electrically connect these members to the terminal 25. The terminal member 30 also has a perforated arm 31 which is separated from the-arm 26 of the terminal 25 by an. insulating washer 32 and is secured in position by a tubular rivet 33 of conducting material which extends completely through the base 'of the socket and is flanged over the terminal member 30 on the outside and over a metal washer 34, which is separated from the ring 23 by aninsulating disk 35, on the inside. Thus, the parts are securely held in position while the terminal 25 is electrically connected with the contact cup while the terminal member 30 is connected to the tubular rivet 33 and the washer 34 which constitute an independent contact within the socket. Thearrangement of the terminal members may be varied to accommodate the service condition under which the socket is to be used.

In mounting the socket on the base plate- 15 the tubular enlargement 12 is thrust through one of the holes 1a in. the plate, as shown in Fig. 1, then the edge of the enlargement is spun over as shown in Fig. 2 to form a substantial mechanical connection between the two parts. This mounting is particularly simple and reliable; it occupies a very small amount of space so that a plurality of sockets may be arranged close together and the distance between them will usually be determined solely by the size of the heating or lighting unit with which the socket is to cooperate.

In order to prevent the contact cup from turning in the cupshaped base these members, when assembled, are correspondingly indented as shown at 36 in Fig. 2, and in order to prevent the base from turning in the plate each of theholes 14. is provided with a notch 37 into which an upturned lug 38 of the flange 13 is inserted. a

3 The. socket contact may be formed in any suitable manner and is not necessarily pro:

I vided with corrugated or screw-threaded bers, and a single means forsecuring the contact members together and to the metal base. i I

2. A contact device comprising a metal base having a rib near one end and a'portion beyond the rib adapted to extend through a suitable hole in a supporting plate and be flanged over to secure the base thereto, an electrical contact member secured Within the base and insulated therefrom,

and a terminal member on the outside of the base, insulated therefrom and electrically connected with the contact member Within.

3. A socket comprising a metal base having an annular rib near one end and a portion beyond the rib adapted to extend through a holein asupporting plate and be flanged over to secure the base thereto, a socket contact secured Within the base and insulated therefrom, and a terminal memher on the outside of the base insulated therefrom and electrically connected With the contact member Within.

4. A socket comprising a cup-shaped metal base having an annular ribnear its edge and a portion beyond the rib adapted to extend through a hole in a supporting plateand be flanged over to secure the base thereto, and a socket contact secured within the cup-shaped base and insulated therefrom, and a terminal member outside of said base and electrically connected With the socket contact Within.

5. A socket comprising a cup-shaped sheet metal base having an extruded annular rib near its edge and a cylindrical por tion beyond the rib adapted to extend through a circular hole in a supporting plate and be flanged over to secure the base thereto, and a socket contact within the cupshaped base and insulated therefrom, a pair of electrically independent terminal members outside of said base and insulated therefrom, and a single contact member constituting means for securing the parts of the socket together.

6. A socket comprising a cup-shaped sheet metal base having an extruded annular rib near its edge and a cylindrical portion beyond the. rib'adapted to extend' through a circular hole in a supporter plate and be flanged over to secure the base thereto, a socket contact within the cup-shaped base and insulated therefrom, a pair of electrically independent terminal members outside of said base and insulated therefrom, a single contact member constituting means for securing the parts of the socket together,

and means for preventing the rotative move-' first named terminal, and a hollow central rivet for attaching the second terminal to the socket and clamping the insulating washers in position to electrically separate the central rivet and the second terminal from the socket, said central rivet constituting an independent contact Within the socket.

In Witness whereof, I have hereunto set my hand this 6th day of May, 191 in the presence of two subscribingwitnesses.
